after using proxy anoying advertise starts to block one of my favorite websites

[tadasdt]

Binary package hint: firefox-3.0

i tried proxy, i used some German server, but it looked very slow for my so i decited not to use proxy. Then i noticed that when i try to open one of my favorite websites (www.hell-music.lt) firefox opens advertise (http://www.hickoryfarms.com/default.asp?campaignType=Redirect&campaignName=SQ%20Redirect). Other websites work very well. Also website that i mentioned works fine with other internet browsers.
